After too much time without updates... I am back again!
I finally managed to finish my new portfolio, it took me longer than expected, but I think it was worth the effort.
There are some new photographs, the look is much nicier, and it is far esasier to navigate;

In this article, I would like to share with you the workflow I have developed, to handle the photos I make using Linux and free software exclusively.
Preparing
I do not follow any specific routine, not even formatting the cards before I start to make photos (except those times when I go on eduperezhttp://www.blogger.com/profile/13263406194235726162noreply@blogger.com6tag:blogger.com,1999:blog-8577951730132414862.post-7345454728119246552009-07-28T10:10:00.008+02:002010-05-28T10:21:42.511+02:00Aging a portrait with GIMPEste artículo también está disponible en Español: Como envejecer un retrato.
There are countless articles available on Internet, explaining how to retouch a portrait and make somebody look younger; basically, what they do is soften the skin and remove wrinkles and other skin defects. In this article I will explain the method I employ to produce exactly the opposite result: aging a portrait.

I had read on Internet about a photographic technique called 'painting with light', which can produce some amazing results. As I waited for the right opportunity to test it myself, a flower bouquet appeared at home, and presented itself as the perfect victim.

In my article HDR and Linux I explained my current work-flow to make HDRs using Linux. Still on that subject, in this article I show a script I wrote to make all that process automatic with a single call.
The source code for such script is:

On night photography, long exposures are the norm: sometimes several seconds, and sometimes several minutes; I also tend to employ HDR techniques, and that means that I often end making series of nine or even more photos all together.

Four months ago, my fist child was born; and as anyone can see here, photography is one of my hobbies... if we mix a proud father (and which father is not proud of his children!?) with a photography enthusiast, the results can be easily imagined: photos and more photos of the child.

Probably, this is the most complex photo that I have made to date, both because the number of exposures required, and because the processing required: to create the panorama which can be seen on the header of this blog, I had to take 27 different photographs, and then process them with a computer during eduperezhttp://www.blogger.com/profile/13263406194235726162noreply@blogger.com5tag:blogger.com,1999:blog-8577951730132414862.post-76522738927981592812009-02-15T00:15:00.021+01:002011-01-20T09:35:36.404+01:00HDR and LinuxEste artículo también está disponible en Español: HDR en Linux.
It has been several years now since I decided to completely delete MS-Windows out of my computer at home.

I had lying around an old Konica lens, completely manual, which has not been used for a long time.
